stackprogramer

this is my source, when i want to when i clicked pressme,the text type mytext
is showed.(the former is hiden).then it wait 1000 ms the main.qml start.

import QtQuick 2.2
import QtQuick.Window 2.1
import QtQuick.Controls 1.2
import QtQml 2.2
import QtQuick.Dialogs 1.2
import QtQuick.Controls.Styles 1.2
Window{id:page1
 function delay(duration) { // In milliseconds
          var timeStart = new Date().getTime();
           mytext.visible=true
          while (new Date().getTime() - timeStart < duration) {
 pageLoader2.source = "main.qml"
          }

          // Duration has passed
      }
 Loader { id: pageLoader2 }

 Text {id:mytext
        Component.onCompleted :{visible:false;}
        color:"red"
        style: Text.Outline;
         styleColor: "yellow"
         font.family: gamefont2.name
          font.pointSize:25;
        text: "<b>Score+10</b>"
        visible:false;


        MouseArea {

            anchors.fill: parent
            onClicked: {


            }
        }
            }
 Text {id:pressme

        color:"red"
        style: Text.Outline;
         styleColor: "yellow"
         font.family: gamefont2.name
          font.pointSize:25;
        text: "<b>pressme</b>"
        visible:true;


        MouseArea {

            anchors.fill: parent
            onClicked: {delay(1000);


            }
        }
            }
}

my problem is the mytext when is show when it qml exit from delay function.
and the mytext has a time 1000 ms that we consider it for showing mytext,it don't show!!!!!!!!!
the text.visible=true don't work!!!!!!!11
how can i fixed it???????

It would help if you give a working source code (the window is not visible, gamefont2 is not defined).

The problem is with your delay function which contains a blocking loop - you really should avoid this and prefer a Timer element for instance...
Anyhow, with the current design, f you want your text to show up, you can set the its visibility in the "pressme" mousearea onClick handler before calling your delay function.

this is some source code not all.

i want to use text.visible in function delay only ,this is my way for special reason.
can you about blocking loop more??

i moved the mytext.visible=true; to MouseArea,now my source is here

import QtQuick 2.2
import QtQuick.Window 2.1
import QtQuick.Controls 1.2
import QtQml 2.2
import QtQuick.Dialogs 1.2
import QtQuick.Controls.Styles 1.2
Window{id:page1
 function delay(duration) { // In milliseconds
          var timeStart = new Date().getTime();
       
          while (new Date().getTime() - timeStart < duration) {
 pageLoader2.source = "main.qml"
          }

          // Duration has passed
      }
 Loader { id: pageLoader2 }

 Text {id:mytext
        Component.onCompleted :{visible:false;}
        color:"red"
        style: Text.Outline;
         styleColor: "yellow"
         font.family: gamefont2.name
          font.pointSize:25;
        text: "<b>Score+10</b>"
        visible:false;


        MouseArea {

            anchors.fill: parent
            onClicked: {


            }
        }
            }
 Text {id:pressme

        color:"red"
        style: Text.Outline;
         styleColor: "yellow"
         font.family: gamefont2.name
          font.pointSize:25;
        text: "<b>pressme</b>"
        visible:true;


        MouseArea {

            anchors.fill: parent
            onDoublClicked: {
			mytext.visible=true;
			delay(1000);
			


            }
        }
            }
}

but the mytext is n't showed.when i toggle comment function delay,it works!!!!!!!
how we can use functions in mousearea!!!!!

stackprogramer

my problem is not solved yet,i concluded i can not i can't use Timer type in javascript function,so i use the method getTime(),mytext is not show now.
this is strange in qml.......

stackprogramer

instead using this delay function in top code:

function delay(duration) { // In milliseconds
          var timeStart = new Date().getTime();
           mytext.visible=true
          while (new Date().getTime() - timeStart < duration) {
 pageLoader2.source = "main.qml"
          }

i uses Timer type for create delay. in onTriggered i call other function in js and my problem is solved.thanks for attention and contribution

@stackprogramer Yes this sounds way much better. Actually, the Timer was the recommandation of my previous comment !

stackprogramer

yes,after some days i did your advice.thanks for contribution
